What you can do

What your AI can do with MCP Selection Lab

Real prompts you can type the moment it's connected — no setup, no docs to read.

“Use “selection_lab_info”: Get free service capabilities, limits, privacy and connection details; does not scan a target.”

“Use “scan_mcp_metadata”: Create a free public report of MCP tool-description routing collisions. Reads discovery metadata (initialize/tools/list) only; never ca.”

“Use “get_selection_report”: Read and agent-enrich an existing public scan report by id; no new target request or model call.”

Security check

How secure is the MCP Selection Lab MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how MCP Selection Lab holds up.

✓ Verified directory serverMCP Selection Lab · railway.app

Official endpoint

Operated by MCP Selection Lab (railway.app) at its documented MCP endpoint — not a third-party mirror or community re-host.

No sign-in needed

This server only exposes public data — no account and no credentials are involved when you connect.

Scanned before it goes live

gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.

Watched for drift

If MCP Selection Lab adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

FAQ

Questions, answered

Is there an official MCP Selection Lab MCP server?

Yes — MCP Selection Lab operates its own remote MCP server at mcp-selection-lab-production.up.railway.app. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.

How do I connect MCP Selection Lab to Claude or ChatGPT?

Add gate's gateway URL to your AI client once, then pick MCP Selection Lab in the directory. No account or sign-in is needed. From then on, MCP Selection Lab's tools are available in every client you've connected to gate.

Do I need to host anything?

No. MCP Selection Lab runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.

Is the MCP Selection Lab MCP server safe to connect?

It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
